Benzoxazole and Benzothiazole Antirust Greases. Work Unit Directive (WUD) 51

Abstract

Peifluoroalkyl and perfluoroalkylether substituted betizoxazoles, benzothiazoles, bisbenzoxazoles, and bisbeazothiazoles have been synthesized and have been extensively tested as antitrust and anticorrosion additives in grease compositions based on fluorine- containing fluids and fluorinated ethylene-propylene (FEP) and polytetrafluoroethylene (PTFE) thickeners. Testing has shown that one percent concentrations of the additives in the grease formulations provide inhibition against rusting of ferrous metal components under conditions of high humidity. Testing in high-temperature environments has shown that corrosion of the ferrous metals is inhibited under these conditions also. Variations in fluid and thickener concentrations or grease consistency had no deleterious or synergistic effects on the inhibiting characteristics of the additives.
